NORTH DAKOTA.

Specification of Letters Patent.

Patented March 27, 1906.

Application filed February 27, 1905. Serial No. 247,545.

To all whom it may concern.-

Be it known that we, ELIAs C. ERB, a resident of Hunter, and ALLEN L.PowLIsoN, a resident of Erie, in the county of Cass and State of NorthDakota, citizens of the United States, have invented certain new anduseful Improvements in Rotary-Disk Plowing Attachments, of which thefollowing is a specification.

Our invention is related to grading and ditching machines and to plows,and has for its object the provision of a rotary-disk plowing attachmentwhich is very durable and perfect working and not liable to wear to anygreat extent by friction.

Our invention consists in the novel features of construction andcombination of parts, substantially as hereinafter more fully describedand specified, and pointed out in the claims of this specification.

In the drawings forming art of this specification similar characters 0reference denote similar parts in all of the illustrations.

Figure 1 represents a front view of our rotary-disk plowing attachment.Fig. 2 represents a rear view of our rotary-disk plowing attachment.Fig. 3 represents a perspective rear view of our rotary-disk plowingattachment: Fig. 4 represents a perspective side view of our rotary-diskplowing attachment. Fig. 5 represents a perspective rear view of ourrotary plowing-disk, showing a central bearing-plate having a centralaxle, and the bearing-plate, showing the circular concave track for thebearing-balls to travel in. Fig. 6 represents a perspective rear view ofour rotary plowing-disk, showing the bearin balls placed in the concavetrack and the ro ler-bearing placed around the central axle. Fig. 7represents a view the same as that shown in Fig. 6, but much enlargedandhaving a part of the plowing-disk cut away. Fig. 8 represents a frontperspective view of our standard and bearing-support having a centralbox for the axle of our rotary plowing-disk and showing the circularconcave track for the bearing-balls to travel in. Fig. 9 represents anenlarged perspective View of the rollerbearing. Fig. 10 represents aperspective view of the washer that is placed next to the outer end ofthe roller-bearing as seen in Fig. 14. Fig. 11 represents a perspectiveview of the washer, the outer end of the axle, the key in the end of theaxle, and the bur on the end of the axle, said bur having cross-slotsfor the key to slide in. Fig. 12 represents a rear view of thedust-excluding cap, the said cap being made of sheet metal and said capbeing s lit radially from its center to its periphery, t us forming aspring-cap. Fig. 13 represents the key that is shown in position in Fig.14. Fig. 14 represents a central sectional view through the plowing-diskand bearings of the plowing attachment and showing a perspective view ofthe socket edge and standard bolted into the socket and also showin aper-,

spective view of the soil-turning mol board scraper having an armattached to the standard.

In carrying out our invention the concave rotary disk A is axled in thebox N of the bearing-support L, which bearing-support has a circularrace or track F for bearing-balls to travel in, and said support L hasan outer stem S and outside socket at S, to which socket is attached thestandard C, the said standard having an arm Y, which arm Y supports amoldboard-scraper T, which said standard is to be secured to the beam ofa rading and ditching machine or wagon- Foading machine or plow.

The rotary lowing-disk A has attached a rear central p ate K, having theaxle B and circular race or track F for the bearing-balls to travel in,which axle B may be cast integral with the central plate or may be madei of steel or wrought metal and inserted or screwed into a central holein the central plate, and which axle B is surrounded by theroller-bearings D, and the circle of balls E are placed into thecircular concave track F. The bearing-support L is placed around theroller-bearing and against the circle of bearing balls. The washer G islaced around the reduced and threaded en P of the axle B and against theend of the bearin part of the said axle. The bur H is secure on thethreaded end of the axle B, and the said bur is held in properadjustment-by the key R. The concave dust-excluding springis sprung intoits place, which place is slightly undercut, so as tohold the said coversecurely over the end of the axle and the bur and key that holds the burfrom revolving on the axle, but allows the bur to revolve with the axle.Thus our rotary-disk plowing at tachment is combined together for use onrading and ditching machines and wagonoading machines and on plows.However, when our invention is used on plows for fieldplowing then thestandard, as herein shown, may be in some cases dispensed with and ourrotary plowing attachment may be connected to the beam of a plow by asuitable arm connected to the outside of the bearing-sup port.
